Facebook Posts Buttons Disappeared

As I was scrolling through Facebook, NONE of the posts (friends, groups, pages, etc.) had the usual Like, Comment, or Share buttons/words to click on.

Less than 30 minutes before everything looked as it should. ALSO, those same buttons disappeared from my own posts (on my page and in the Facebook feed). I didn’t make any changes—and I’ve double-checked my settings/preferences. What’s going on?
